DUST-COLLECTOR.

- Specification of Letters Patent. Pate t d Dec. 10, 1918.

Application filedJ'anuary 22, 1916. Serial No. 73,569.

To all whom it may concern Be it known that I, TRUMAN C. Srmn- WOOD, a citizen of the United States, and a resident of Watseka, county of Iroquois, and State of Illinois, have invented certain new and useful Improvements in Dust-Collectors, of which the following is a specification.

My invention relates to improvements in dust collectors and more especially to improvements in such devices especially adapted for use in hot air heating systems and has for its object the supplying of an im proved quality of air through such systems.

The invention consists in the combinations and arrangements of parts hereinafter de scribed and claimed.

The invention will be best understood by reference to the accompanying drawing forming a part of this specification, and in which Figure 1 is a longitudinal section illustrating the system embodying my invention, and

Fig. 2, a transverse section taken on line 22 of Fig. 1.

The preferred form of construction as illustrated in the drawing comprises a shallow pan 3 which is open at the top and is provided with a central transverse partition at extending across the upper portion thereof as shown leaving a space 5 under said partition for the passage of air. The lower portion of partition at is provided with a plurality of perforations 4 and woolen streamers or strings are secured to said perforations to hang in the passage 5, said streamers being saturated with a disinfectant. A. baffler 6 in the form of an inwardly and downwardly turned flange is arranged at the outlet end of said pan and a deflector 7 is hinged to the inlet end thereof. The pan is designed to be inserted between adjacent floor joists 8, being of a width to fit loosely therebetween and of a height at the center substantially equal to the height of the vertical space between said joists. In installing the system a transverse board or other closure 9 is arranged across the space between two adjacent joists 8 extending in convenient relation to the furnace, and a depending cold air furnace return pipe 10 is connected with the other end of said space, thus practically converting said space into a part of the cold air return system of the furnace. A removable registei 11 is arranged in the flooring above the space between joists 8 and immediately adjacent closure 9.

In use the bottom of pan 3 is covered with oil and the same is inserted in the passage between joists 8 through the opening obtained by the removal of the register 11 and deflector 7 positioned as shown to deflect air entering through register 11 through the pan 3 to pipe 10. It will be observed that the lower edge of partition 4 is located at a level well above the level of the lower end wall of pan 3, so that any liquid poured into said pan will overflow said end wall before covering the lower edge of said partition, thus insuring a free passage under said partition. The air passing through pan 3 will be deflected by the partition 4 into intimate contact with the bottom thereof and the oil therein, thus removing a large portion of the dust from said air, which then in its natural course passes out through the pan, however any solid particles of dust still remaining being trapped by baflier 6 and caused to deposit in the pan. The pan may be readily removed for cleaning as often as desired. By this arrangement the cold air returning to the furnace will be freed from dust and other impurities thus greatly increasing the quality thereof.

While I have illustrated and described the preferred form of construction for carrying my invention into eflfect, this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

Having described my invention what I claim as new and desire to secure by Letters Patent is:

1. A dust collector comprising a shallow pan open at the top; and a partition extending substantially centrally across the open top of said pan, the lower edge of said partition being located above the top of one of the end walls of the pan, substantially as described.

2. A dust collector comprising a shallow pan open at the top; a central partition extending substantially centrally across the upper open portion of said pan; and

streamers secured to and hanging below said secured to and depending from said parti- 10 partition, substantially as describedtion, substantially as described.

3. A dust collector comprising a'shallow In testimony whereof I have signed my pan open at the top and having its sides exname to this specification in the presence of tending centrally Well above the ends of said two subscribing Witnesses.
